IMPROVEMENT IN CORN-SHELLERS.

'The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, J. P. SMITH, of Hummelstown, in the county ofDauphin, and State of Pennsylvania, have invented an ImprovedOorn-Sheller; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, making part of this specification.

Figurel is a side elevation of the corn-sheller;

. Figure 2, a top view thereof.

Figure 3, a side view of the bench or stand, and stationary concave-ortube-plate attached thereto, the shelling-wheel being removed.

Like letters designate corresponding parts in all the figures.

This is a hancl-sheller, composed of a bench, A, with a seat, a, aconcave or tube shelling-plate, B, attached tothe side of the bench, anda shelling-wheel, G, provided with shelling-teeth, and revolving inproximity to the stationary shelling-plate, toward which it is pressedby a spring, '5, on its shaft, 0, so that the space between theshelling-wheel and shelling-plate may vary accordingto the size of thecar, while shelling.

The cars are fed into a nearly vertical tube or concave, d, in the faceof the shelling-plate, down which tube the action of the shelling wheelforces them; thence they are turned, by the circular action of theshellingwheel," sidewise, along a space, f, at the bottom of theconcave, into a second tube or concave, g, through which they are causedt5 ascend by the action of thesaid shell-.

ing-wheel; and, finally, the shelled cobs are ejected at the topthereof, to be taken away.

The face of the shelling-wheel 0, except where otherwise occupied, isprovided, at suitable distances, with pointed teeth, Z l, substantially.as'shown, and they require no further description. v

I employ a'set of oblong, and, preferably, somewhat forwardly-curvedteeth, mom, situated obliquely on the face of the shelling wheel, nearits periphery, and provided with notches, o 0, in their sharp ridges.

- Their oblique inclination is forwardat their outer extremities, in thedirection of the motion of the wheel, and their function is not only toassist in removing the grains of corn,-but to impart a slowly-revolvingmotion to the ears of corn, as well as a forward-feedingmotion, thecombined .eflect of its action, in connection with the concaves or tubesd being to move the upper ends (at start) of the ears'around, as itwere, in the arc of a circle, or in curves, approximating as nearly asthe shape of the stationary tubes which they traverse will allow. Thus,if the tips of the ears are inserted downward in the tube or concave d,the effector the obliqueteeth m m on' the cars will be to move the butsfastest, or in the outer curves of the circuit traversed, while the tipswill continue to hug the inner edges 0 e of the tubes or concaves. V

The first feature of improvement consists in a set of pointed teeth, nn, near the shaft of the shelling-wheel, being not merely flat butconcave on their front sides,

so that they willsurely seize the ears and move them forward, aswell asassist in removing the grains of 7 corn. These teeth act upon thetipsand inner sides of the ears, and serve'to givea slow feeding motion tothose parts, whilethe more rapidly-moving teeth'm'm. are feeding thebuts of the ears round in their enlarged circuit.

The second feature of my invention consists in a set of teeth ornotches, h h, at the upper edge of the connecting-space j, between thetwo tubes or concaves d and g, for the double purpose of completelyshelling off all grains of corn on the extreme tips of the ears, and tofurnish a retarding-fulcrum or-rest, against which the tips of the earsbear, as the shelling-wheel is bringing the buts of the ears round fromone concave to the other.-

What I claim as my invention, and desire to secure by Letters Patent,is-

The teeth n n, near the shaft of the shelling-wheel, arranged andoperating, in combination with the concave plate, substantially as setforth.

Also, the notches h h on the concave plate, ar-.- ranged and operating,in combination with the shellingwheel, substantially as and for thepurpose herein specified. a The above specification of my improvedcorn-sheller signed by me, this 21st day of April, 1868.
